Scottish fiddler Benedetti, who will perform at the opening ceremony of the Commonwealth Games in Glasgow, said: "I am absolutely thrilled to have reached the Top 20, not something a classical artist ever expects.

"This is a deeply personal recording - inspired by Bruch's Scottish Fantasy the project took me deep into the heart of Scottish culture.

"I hope the music, in all its diversity, is providing some uplift and pleasure."
